You also get three months free, and orders above $US15 can be delivered in the same day.

That’s a paltry sum for the amount of time and energy I’m saving.

The Interface

Shopping Express has an iOS app, an Android app, obviously, and it’s available on the web. It’s pretty straightforward to use, and the interface looks just like any shopping site.

Setup is easy. You link it with your Google account and a credit card that’s stored in Google Wallet. And then you get to do the fun part: Shop. And you can share your account for free with one other person who lives in your house.

I live just south of San Francisco, on what’s called the Peninsula (and just a little north of Google’s campus in Mountain View). Google Shopping Express is available in San Francisco, the Peninsula and San Jose, West Los Angeles, Manhattan, Chicago, Boston, and Washington, D.C.

You can also order alcohol if you live in the Bay Area, but someone with a valid ID needs to be at home when the order is delivered. And you can enter store reward and membership card numbers.

You then pick when you want the order delivered, choosing among 3- or 4-hour blocks throughout the day. You also can leave delivery instructions, and you can let them know whether you’ll accept a substitution if the store is out of your first choice.

The Competition

There are a few things that Shopping Express lacks that others have. AmazonFresh offers 1-hour time slots. It also allows you to order fresh groceries, such as meat and eggs, and milk. And you can order frozen foods.

AmazonFresh offers a free 30-day trial, and then you will be charged $US299, which includes all the benefits of Prime. You then get free same-day delivery on orders over $US35.

Instacart also offers a membership, called Instacart Express, as well as fresh groceries. For $US99 per year, you get free shipping on orders $US35 and over. There’s a free 14-day trial so new customers can determine if it’s right for them.

You don’t have to sign up for a membership if you don’t want to and can pay a la carte. Your first order is free, and then you pay different prices depending on how quickly you want your items. For example, if you need something in the next hour, you pay $US5.99 per order that’s $US35 or more, but if you can wait a couple hours, it drops to $US3.99. And orders less than $US35 cost more.

But that three-month free trial period that Google offers is hard to beat.

If a mistake happens, there’s no need to return the item. You can keep it or donate it. If the correct item is available, you choose a new delivery time and they will deliver in the time block you specify.

If the correct item isn’t available, you get a full refund. And you get to keep the vanilla almond butter! Not bad.

Because its service isn’t competing directly with grocery stores — on the contrary, it’s sourcing all of its groceries from stores near you — it’s only a matter of time before other stores partner up with Google to offer an even larger breadth of products. With the announcement on Monday, Google says that its added 16 more merchants just within the last few months.

And the service itself is great: Glass jars are wrapped nicely in paper. Things that could potentially leak all over your stuff are sealed in a plastic bag.

If I coupled Shopping Express with one of the other sites that delivers fresh groceries, I could see myself never leaving the house for groceries again.

I’ve reached peak laziness. And I’m definitely OK with that.
